As a GM, often a fantastic ending to a campaign comes to me before I start it. In the Star Wars universe, I picture the heroes stealing a Star Destroyer from the Empire or, in D&D, I picture the heroes resurrecting an elder dragon.
Many times, campaigns are formed because of these inspirations… And my heroes never get to experience it because the campaign either takes on a life of its own or fizzles out. Or worst of all… I come up with something different.
How can I get low-level, beginning heroes to these endings? I feel that bringing such epic scenes early breaks realism, and I have no desire to begin a high level campaign. I'm trapped between that and the reality that planning out every plot detail from the beginning to the end is a waste of effort due to the effects of a campaign mentioned above.
Has anyone encountered this problem in the past and how has it been addressed?
